Now it's used by ignorant (and often prejudiced) people to describe something that they don't like. It's especially common among teenage boys, who use it to look cool or to "hide" their insecurity about gay people.
Gay is now slang for a homosexual person, that is, somebody who is attracted romantically and sexually to people of their own sex.
Gay men are known as gays, while gay women are known as lesbians. And some bisexuals also identify as gay.
Up to 1 in every 10 adults is predominantly gay; everybody is somewhere in between the two extremes of heterosexual and homosexual.
Gay is only sometimes, but not always:
-Living with AIDS.
-Living a promiscuous life.
-Acting very much like the opposite gender (very masculine women and very feminine men.)(When people think of these stereotypes, they're usually thinking about transsexual people or transgender people instead. Most of these people are straight and just happen to identify as the opposite gender.)
-All about sex.
Being gay is not an illness or a perversion; it's a totally normal variation of human sexuality and it's been around for countless ages, not to mention existing in many different species of animals. In fact, heterosexuals could learn some things from gays, bisexuals, transgender people, pansexuals, asexuals, and other queer people... if they would only put their prejudice aside and look at them as people.
Gay men don't take any women from the straight men looking for a lady and vice versa with lesbians and straight women... and lesbians (and sometimes gay men) provide something exciting for the straight men and women to watch... same-sex kisses.
Gays are perfectly normal people. Their only "difference" is that they (romantically) love somebody of their own sex. Aside from the cruel prejudice that they face because of who they love, they usually are able to live wonderfully full, happy lives.
Often, gays have reclamed old derogatory terms for them as terms of affection: fag and queen for the men, dyke for the women, queer for anyone from the non-heterosexual community, etc... although they can still be used as insults by the bigoted.
Gays sometimes do imitate heterosexual gender roles (butch and femme) in their marriages (in every other way if not legal), but most do not; plenty of femmes pair up with other femmes, butches with other butches, androgyny and so forth. It's often remarkable how much their unions resemble heterosexual unions.
A man can be highly flamboyant and act and dress quite feminine, but sleeping with men is the last thing on this mind. Likewise, a man can be incredibly butch and swaggering, and yet he likes to sleep with men; being gay has to do with who you are attracted to sexually, not how masculine or how feminine you are.
Gay is not all about sex. Most gays are happy doing other things than sex. And most gays loathe the idea of molesting a child, contrary to the beliefs of ignorant people. (Almost all pedophiles are heterosexual)
And with marriage ending in so many divorces, then those in favor of marriage should be happy that there are people who want to get married and are willing to fight for that right. Gays have had to fight so much for the basic rights that straights take for granted.
-"Yes! Quite nice to look at!"
-"Aw man, this computer is being so gay! It won't let me print!"
-"Hey, what was that for?!"
-"You are being so straight!"
-"Scott... I have to tell you something very important...
-"What is it, Colin?"
-"I- I'm gay."
-"That makes two of us."
-"You are?!... Then are you comfortable knowing...?"
-"That I love you..."
-"I- I'll leave you alone if you want me to...!"
-"No, stay! Joe..."
